It looks like Android users should be weary when downloading a free app since fifty percent of the time the app will not post its privacy policies. This is a strong statement, but a study done by the Carnegie Mellon University proved that over half of the free apps listed on Google’s Play Store don’t have privacy policies.
Taking in consideration that there are around 18,000 free apps available on the Play Store, over 9,000 of them are violating privacy policies.
The Carnegie Mellon University study contained a bunch of interesting information but what stood out the most is that free apps are likely to gather personal information without notifying the user and more interesting is that apps share the user’s information with others.
Right now all we can do is to wait for Google to take matters into their own hands, but until then Android users should pay attention to what they are downloading. This might not seem such an important matter, but it actually is mainly because none knows with whom are these apps sharing user identification information.
